RAZOR-STROPPING DEVICE.

On the spindle strop, thereby preventing the edge of the blade O a friction-roller F, covered with leather, from cut-ting into the strop in case the blade rubber, fabric, or any other suitable material is moved along the strop while not pressing that produces friction, is rigidly mounted, and on the roller F, so as to produce the necessary I00 50 on the spindle D a longitudinally slotted friction. In case more friction is desired two blade-holder G is mounted, which is adapted friction-rollers F may be provided, one at each side of the blade-holder, as shown in dotted lines in Fig. 3.

In case an ordinary razor is to be stropped the handle P must be held in line with the blade, and this is accomplished by drawing a rubber tube over the joint, as shown in dotted lines in Fig. 1.

If desired, the friction-roller may be made smaller and grooved, as shown at F in Fig. 6, in which case the friction-roller travelson a separate friction-piece at the side edge of the strop, so that when the direction in which the implement is moved is reversed the blade will also be reversed and turned on its back.

If desired, a grooved friction-roller F may be applied on the blade-holder itself, as shown in Fig. 7, and over said pulley a cord is to be passed, which is arranged at the side of the strop, or the cord can be passed over the roller and an additional roller F on an arm .of the handle.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1.. In a razor-stropping device, the combination, with the blade-holder, of a spindle adj acent to the blade-holder and carrying a friction-roller, and gearing for transmitting .motion from the spindle carrying the frictionroller to the blade-holder, substantially as set forth.
